09/06 – Brantly’s “Dry and Sunny for Labor Day” Sunday Night Forecast

The residual dry air, mostly clear skies and very light to calm winds tonight should allow for a longer duration pleasant period starting right around sunset. This is much earlier than last night when the weak cold front and dry air did not really get into the region until late in the night. Lows are forecast to drop below 70 again generally for the Mississippi Gulf coast areas north of I-10.

The drier air will generally remain in place for Labor Day, however some periods of higher dewpoints near or above 70 will likely move back north over areas south of the tidal lakes, and there could be enough seabreeze forcing, moisture and instability for a few afternoon showers and thunderstorms to develop. Overall though, rain chances are pretty low at less than 20 percent in coverage. A bit more humidity will return due to more east to southeast winds Tuesday. Seabreeze boundaries should bring isolated to scattered, daytime heating driven showers and thunderstorms to most areas Tuesday and that trend should continue into Wednesday with even higher coverage of showers and thunderstorms expected.

In the tropics, the National Hurricane Center is monitoring five different disturbances this Sunday evening. The two red systems in the eastern Atlantic are expected to become tropical depression during the next day or so, while the others, the yellow highlighted areas, have lower chances. None of the systems being watched are an immediate threat to the Gulf Coast for now.
